Abstract

Purpose

Behaviour in virtual learning environments (VLE), including travel, gaze, manipulate, gesture and conversation, offer considerable information about the user's implicit interest. The purpose of this study is to find an approach for user interest mining via behaviour analysis in a VLE.

Design/methodology/approach

According to research in psychology, any interaction in a VLE has implications for the user's implicit interest. In order to mine a user's implicit interest, an explicit interaction‐interest model needs to be established. This paper presents findings from the concept classification of behaviour in a VLE. Based on this classification, the paper proposes a hierarchical interaction model. In this model the relation between interaction and user interest can be described and used to improve system performance.

Findings

In the experimental prototype the authors found that user‐implicit interest could be mined via stages of web mining, i.e. capture the user's original gesture signal, data pre‐process, pattern discovery, interaction goal and interest mining. The mined user's interest information can be used to update the state of local interest, leading to a reduction in network traffic and promotion of better system performance.

Originality/value

This is an original study using behaviour analysis for interest mining in e‐learning. Research on interest mining in e‐learning focused on content mining or search engine and usage mining in web courses. The paper provides valuable clues regarding user interest mining in a VLE, in which the context is different from usual web courses. The research output can be implemented widely, including online learning, and especially in the VLE.

Abstract

Pervasive computing envisions seamless support for user tasks through cooperating devices that are present in an environment. Fluctuating availability of devices, induced by mobility and failures, requires mechanisms and algorithms that allow applications to adapt to their ever‐changing execution environments without user intervention. To ease the development of adaptive applications, Becker et al. (3) have proposed the peer‐based component system PCOM. This system provides fundamental mechanisms to support the automated composition of applications at runtime. In this article, we discuss the requirements on algorithms that enable automatic configuration of pervasive applications. Furthermore, we show how finding a configuration can be interpreted as Distributed Constraint Satisfaction Problem. Based on this, we present an algorithm that is capable of finding an application configuration in the presence of strictly limited resources. To show the feasibility of this algorithm, we present an evaluation based on simulations and real‐world measurements and we compare the results with a simple greedy approximation.

This study aimed to explore how a group of Chinese primary mathematics teachers learned through conducting an online cross-cultural lesson study between China and Australia.

Abstract

Purpose

This study aimed to explore how a group of Chinese primary mathematics teachers learned through conducting an online cross-cultural lesson study between China and Australia.

Design/methodology/approach

An expansive learning theory was adopted to examine teachers' learning through collective activities across different activity systems. Multiple data sets including videos of research lessons, debriefings and audios of interviews were collected. From the expansive learning perspective, based on a fine-grained qualitative data analysis, various contradictions (as driving forces of learning) were identified and the ways of resolving the contradictions (as enactment of learning) were located to feature teacher learning throughout the online lesson study process.

Findings

Teachers' expansive learning includes enhancing teachers' MKT and Mathematics TPACK, developing instructional design skills and capabilities in addressing challenges occurring in the virtual environment were identified.

Research limitations/implications

Theoretically, the study illustrated how expansive learning theory could be utilized to examine teacher collaborative learning in the online cross-cultural lesson study. Practically, this study showed that reiterative cycles and experts' facilitation are crucial to expansive learning for linking research to classroom practice. However, this study did not focus on student learning in the virtual environment. Australian teachers' reciprocal learning through the online lesson study also requires further exploration.

Originality/value

Both online lesson study and cross-cultural collaboration are innovative. The expansive learning lens are creatively used to examine the complexity of teacher learning in such a novel environment.

Abstract

Purpose

The purpose of this paper is to introduce an innovative theoretical, numerical and experimental investigations on the HP NGD function. The identified HP NGD topology under study is constituted by first order passive RC-network. The simulations and measurements confirm in very good agreement the HP NGD behaviors of the tested circuits. NGD responses with optimal values of about -1 ns and cut-off frequencies of about 20 MHz are obtained.

Design/methodology/approach

The identified HP NGD topology understudy is constituted by a first-order passive Resistor-capacitor RC network. An innovative approach to HP NGD analysis is developed. The analytical investigation from the voltage transfer function showing the meaning of HP properties is established.

Findings

This paper introduces innovative theoretical, numerical and experimental investigations on the HP NGD function.

Originality/value

The NGD characterization as a function of the resistance and capacitance parameters is investigated. The feasibility of the HP NGD function is verified with proofs of concept constituted of lumped surface mounted components on printed circuit boards. The simulations and measurements confirm in very good agreement the HP NGD behaviors of the tested circuits. NGD responses with optimal values of about −1 ns and cut-off frequencies of about 20 MHz are obtained.

Abstract

Purpose

This paper provides a researcher's account of fieldwork experience in conducting audit research in China. By illustrating on-site fieldwork encounters, the paper reflects stages of access negotiation and management in the fieldwork, reveals the researcher's embodied “affects” in the fieldwork and reasserts the value of researcher's openness and attention in the fieldwork.

Design/methodology/approach

This paper uses autoethnography as its overall epistemology. Fieldwork diaries and vignettes are written in the first-person voice to present the researcher's embodied account of fieldwork experience, researcher’s learning and coping skills in managing the fieldwork.

Findings

The research findings are not detached from the researcher's experience of the fieldwork. The fieldwork experiences in this study highlight that the fieldwork access is an ongoing process. Different stages of access negotiations, from rejection to acceptance, reveal the tensions between researcher and participants. This study draws attention to the online platform, WeChat, in connecting with auditors to learn from them and suggests openness to the fieldwork encounters and a resilient engagement with auditors.

Originality/value

In reflecting on the researcher's transformation during the fieldwork, this paper argues for a relational and engaged way of conducting fieldwork, rather than a disengaged and judgemental approach in studying auditors' working lives. The paper pays attention to fieldwork as a process and how the knowledge learned in the field is infused with researcher's fieldwork experiences.

Abstract

Purpose

The Li & Fung Group, a century-old, family-controlled multinational group of companies based in Hong Kong, seems to be an exception to the traditional perception of Chinese family business. The aim of this paper is to explore why this company can overcome the fatalism that “family business could not pass on over three generations”.

Design/methodology/approach

This paper will use in-depth case study as key methodology for exploring key research question of family business sustainability. Archival data, including company registration records, newspaper reports, biographical materials and company annual reports, etc., are major secondary data that will be used for qualitative analysis.

Findings

The important findings in this paper is that the authors can identify key ways for solving family conflict and business continuity. Through in-depth study, the authors argue that because Li & Fung can effectively adopt the “pruning the family tree” mechanism and “listing and de-listing” mechanism during critical stages of succession and development, it has flourished for over a century and is therefore a model for other Chinese family businesses to follow.

Research limitations/implications

Because the authors did not conduct personal interviews with the family members of the company, the authors do not have “insiders’ view” on the company development. Also, it is a century-old company, and many historical data cannot be obtained, so some of the developments would not be fully explained and understood.

Practical implications

It can let family business owners, staffs working in family business and professionals serving family business know better that although there are negative sides of family business, their positive sides should not be underestimated. If a proper mechanism can be rightly executed, its negative side could be large reduced, whereas its positive side could be better enhanced.

Social implications

This paper can offer insightful implication to the society that family business, in fact, is highly dynamic. It not only creates jobs by offering services and producing goods but stimulates economic development as family the fertile ground for breeding entrepreneurship.

Originality/value

There is no analysis in the academia in exploring the Li & Fung Group’s development from the perspective of leadership and ownership competition. So, the originality of this paper is very high.

Abstract

This article outlines contingent claims created as a result of the arrangements underlying the transfer of state‐owned commercial banks’ non‐performing loans to asset management companies. An understanding of these factors is central in analysing the potential for China’s as set management companies to realise value from their acquisition of these nonperforming state‐owned enterprise loans. After establishing the scale of the non‐performing loan problem, the article identifies and describes a number of real and financial options that may assist in the consideration of the value of assets associated with the transfer of non‐performing loans from the state‐owned commercial banks to the asset management companies. Real and financial options appear in the form of implied guarantees over asset management corporation debt, implied guarantees associated with the non‐performing assets remaining with the stateowned commercial banks, and within the equity positions held by the asset management companies as a result of equity‐for‐debt swaps initiated under the current reform process. The article concludes that any gains made to the credit standing of the state‐owned commercial banks reflect the value of implied guarantees over both the asset management corporation debt and the remaining stock of non‐performing loans held by the banks. Furthermore, institutional arrangements associated with the equity positions held by the asset management corporations significantly reduce the value of options associated with operation and control of firms in which the equity positions are held. Additionally, the structure of equity positions taken under the equity‐debt swaps suggest that the value of equity positions held in state‐owned enterprises by the asset management companies will be considerably lower than hoped for and implied in the asset management companies’ mandates.

Abstract

A large number of residential buildings in hot summer and cold winter zone of China are non-energy efficient with poor indoor thermal conditions. Retrofitting residential buildings with energy efficiency measures is thus important for residents. However, this work progressed slowly because practically applicable measures that not only have high energy savings but also improve indoor thermal performance have not been studied. Thus, this paper carried out a simulation study on the selection of suitable energy saving measures for residential buildings in hot summer and cold winter zone of China. Five potential energy saving options are considered and the energy, indoor thermal comfort and economic performance are compared. The results show that adding movable solar shades is the optimum option with all performance indices ranking first. Meanwhile, this measure is also the only acceptable energy saving solution for residents since its payback period is less than the lifespan of a building. As a conclusion, it is recommended to use movable solar shades as a first priority when retrofitting residential buildings.

Abstract

Examines the extent to which social policy adopted by the colonial government in Hong Kong (prior to its hand‐over China in 1997) has set the agenda for the government of the newly formed Special Administrative Region (SAR). Chronicles the historical development of social policy in Hong Kong since the inception of the colonial government in 1842; identifies that, with the exception of a short‐lived period of expansionism (stimulated by social unrest in the mid‐1960’s) social welfare provision appears to have been low on the government’s agenda and incremental in nature ‐ the emphasis being on economic growth, rather than public spending on welfare programmes. Examines the strengths and weaknesses of this incremental approach; outlines the commitment of the SAR government to the market economy and its proposals for a modest increase in welfare provision, essentially building on the legacy left behind by the colonial government.
